Common mistakes around CRP Check

CRP (C-reactive protein) is a non-specific marker of inflammation. A common mistake is testing during an acute infection or after intense exercise, which can temporarily elevate levels. Another error is interpreting a mildly elevated hs-CRP as a direct indicator of cardiovascular risk – it is only an adjunctive risk factor, not a diagnosis. Many consumer lab tests offer CRP without accounting for time of day, fasting status, or individual baseline. Additionally, CRP is influenced by smoking, obesity, sleep deprivation, chronic inflammatory conditions, and even periodontal disease. A single measurement is of limited value; trends and clinical context matter more. Evidence for routine CRP screening in healthy individuals is moderate. Caveat: Do not self-treat based on a single biomarker; medical interpretation is essential.
